PMID 39656161WHAT IT FOUND
In acute or subacute vestibulopathy, higher fear avoidance beliefs strongly correlate with lower physical activity.
This link disappears in the chronic phase. Assess fear avoidance early to identify patients at risk of inactivity, as it explains a large portion of activity variability in the acute group.
Key findings
01Fear avoidance beliefs were the strongest explanatory factor for total physical activity in the acute/subacute group, but showed no significant association in the chronic group.
02In the acute/subacute group, fear avoidance, etiology, and gender together explained 54.7% of the variability in total physical activity time.
03Participants with acute/subacute vestibulopathy had significantly higher fear avoidance scores and lower total physical activity compared to those in the chronic phase.

What it does not show
The study used a convenience sample without prior power analysis. Participants were artificially classified into acute/subacute and chronic groups based on a 3-month cutoff, which may not reflect the continuous nature of recovery. Physical activity data were extrapolated to a full week for some participants who wore the logger for fewer than 7 days. The study design is cross-sectional, so it cannot prove that fear avoidance causes lower physical activity or vice versa. Complications from surgery (e.g., headaches) were not systematically monitored, which could influence activity levels in the iatrogenic group.
Declared interests
The authors declare no conflict of interest.
The easy way to misread this
Do not assume that fear avoidance beliefs are the primary driver of physical inactivity in all patients with vestibular disorders. The association was strong only in the acute/subacute phase; in the chronic phase, fear avoidance did not significantly predict activity levels, so using it to explain inactivity in long-standing cases may lead to incorrect treatment targets.
